This study investigates the potential of Cassia fistula (Golden shower) as a precursor for activated carbon synthesis using K₂CO₃ activation, leveraging its organic properties known for high porosity and adsorption capacity. This research aims to investigate the feasibility of utilizing Cassia fistula-derived activated carbon (GSAC) for isoniazid removal from water. The study encompasses a two-step activation process—chemical and physical—with varying parameters to optimize surface area and porosity. The carbonization process involves hydrothermal and pyrolysis techniques with controlled conditions. The temperature used in this study is based on the TGA analysis to examine its thermal stability. Batch experiments examine the adsorption equilibrium and kinetics of isoniazid onto GSAC samples, revealing high adsorption capacity and rapid equilibrium attainment by GSAC 1:1 (700°C). The study culminates in the identification of a strong chemical bond between GSAC and isoniazid, implying efficient adsorption potential as confirmed by FTIR and SEM analysis before and after adsorption. The adsorption characteristic is examined with an isotherm and kinetic model. The highest predicted GSAC capacity reaches 219,807 mg/g, emphasizing its promising adsorption capabilities. This work underscores Cassia fistula-based activated carbon as a viable, cost-effective, and eco-friendly adsorbent for isoniazid removal, with implications for diverse applications. The synthesis process parameters, activation methods, and insights into the adsorption mechanism contribute to the understanding of effective adsorbent production and enhance the potential of activated carbon for various industrial contexts.</p></div>","PeriodicalId":21926,"journal":{"name":"South African Journal of Chemical Engineering","volume":"50 ","pages":"Pages 189-199"},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1026918524000970/pdfft?md5=cbb837d5230a8b21c88c86612f4949bf&pid=1-s2.0-S1026918524000970-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142049733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modelling particle separation in a Teeter bed separator from the first principles of particle mechanics and fluid dynamics has been challenging due to the complex interactions of forces acting on particles in varying flow regimes. So, the size recovery curve is a viable option for assessing the separation performance of this separator. This investigation systematically examines the suitability of the Teeter bed separator in reducing the alumina content in Indian iron ore fines. Thorough experimentation and statistical analysis confirm the separator's suitability for beneficiation. Careful consideration was also exercised in choosing a suitable mathematical model to characterize mineral size recovery curves. In this research work Modified Hyperbolic Tangent model, Hyperbolic Tangent model, Weibull model, Rosin-Rammler type model, Erasmus model, and Power function model have better fitted for size recovery. Out of which the Modified Hyperbolic Tangent models for all the data sets indicated the better ability to fit the size recovery data than other models. This innovative approach aligns with the principles of circular economy, aiming to optimize resource utilization and minimize waste throughout the production process. Furthermore, a suitable mathematical model is selected to represent the size recovery curves for minerals by adopting the statistical analysis approach to describe the process.

Catalytic hydrogenation of CO₂ into value-added chemicals and fuels including methanol is one of the attractive environmentally friendly ways to valorize carbon-containing feedstock and reduce global CO₂ emissions. However, enhancing catalytic activity to achieve high methanol yield and selectivity while maintaining stability remains a major challenge. This study investigated the promotion of Cu/MOF-5 catalysts with varying loadings of ZrO₂ to determine its effects on catalytic performance in CO₂ hydrogenation. The copper loading was kept constant while the ZrO₂ content on the MOF-5 support was varied via the impregnation method. The addition of ZrO₂ was found to influence the BET surface area, suggesting the presence of amorphous ZrO₂, as its crystalline phases were not detected in x-ray diffractograms. Catalytic results demonstrated that ZrO₂ addition enhanced the catalytic activity, with increased CO₂ conversion up to 13.2 %. The results showed a correlation between catalytic performance and the reducibility of the active metal, driven by the amount of ZrO₂ present. The catalyst with the highest ZrO₂ loading exhibited the best performance, attributed to its increased surface area and enhanced reducibility. Under optimized conditions (GHSV of 1350 h⁻¹, temperature of 200 °C, and pressure of 30 bar), the catalyst achieved 100 % methanol selectivity.

The formation of secondary porosity distinguishes it, reduction of alkali and alkaline earth metals, removal of impurities, transformation of symmetric to asymmetric strains, increase in acidity, and most importantly, the occurrence of dealumination and desilication processes as the cause of the achievement of these indicators.
